All of this is great advice. In general if you take the "road less traveled" and go off on your own trying to design things yourself it takes a lot more time and money than going with what already is available and works. If you are unfamiliar with this type of thing then maybe you should consider Island Turbo and their 2 turbo set-up. They can be reached @ 800-303-1924, This is not a plug, only a possible option if you are going in this direction. If you are not doing the actual work yourself but instead are going to have a shop experiment for you then you should have "deep pockets" as they are going to be learning on your dime. Also this is a case where "If a little is good a lot is better" NOT!!!!!! Any boost over 6 PSI will damage your engine, less if the mixture leans out or the timing is too advanced. I also don't think an automatic should have forced induction. The transmission in the Delorean is not robust enough to live a long time especally if you push it hard. The manual is more rugged and even it will be damaged by rough handling. No less an authority than Fred Dellis (of Legend Industries) has said that they could get all the power out of the PRV-6 that they needed, the weak point is the transmission. DMC spent MILLIONS with Legend Industries and they could not get around the transmission problem. The long term answer (acording to Fred) was that they were planning to get away from the French and source another transmission and final drive. If you do boost the engine remember to to something about the vacuum modulater on the automatic transmission (it need vacuum to soften the shifts).
